Ailments arising from illusive vision,[3] from hearing, and. from the deity,[4] and mental aberration,[5] and enthusiasm[6]—these five are roots of bitterness which tend to embarass the religious meditations of yogis. The ailment arising from illusive vision is such to a yogi because in it appear Vedic matters, poetic matters, science and the mechanical arts without end. The ailment connected with hearing is so-called because he perceives the meanings of sounds in all their completeness, and he receives sound from thousands of yojanas. The wise call that ailment one from the deity, as in the case of a madman, when like a god he sees all around and in the eight directions. When the yogi’s mind wanders without support through his own fault by reason of his fall from all the rules of good custom[7]—that is well known as mental aberration. When the seething whirl-pool[8] of knowledge like a whirl-pool of water engulphs the mind—that ailment is called enthusiasm. All beings of divine origin, when their religions meditation is destroyed by these great and terrible ailments, revolve again and again.
